Stars Who Played the President

Paul Giamatti

Giamatti starred as the titular character, John Adams, in the 2008 HBO miniseries. The actor later starred as King John in 2011 Ironclad and told Time Out Boston in March 2011, "That's what I look for — crappy world rulers. They were both really bad at their jobs. So I'm not sure, I think John Adams is a step down from King John, actually."
